not sure this is an RA25 or not, but you're in luck with this car showing up on ebay at the moment:
1973 Toyota Celica - Ebay Motors
I'd grab all those ref-pics as you can, making sure you "Enlarge this Picture" when you do that.
IMO, Ebay Motors, albeit slow to get the results you're looking for, is potentially the best darn picture reference site out there.
